The 23-year-old left-hander was called up on Tuesday from Triple-A New Orleans, after posting a 2.63 ERA (47 ER in 161 IP) in 27 starts between New Orleans and Double-A Jacksonville.

Flynn said that after getting an invitation to Spring Training with the Marlins, he wondered if he would get his first callup in 2013.

"I had a pretty good year and everything, and you hope when you get a big league invite to camp [that your debut] comes around this year. … I was really hoping to make it happen this year and get my feet wet at the end of the season."

Flynn will get that opportunity in a ballpark that he has always admired.

"To find out it was [going to be at Wrigley Field] was even better," he said. "It's a great ballpark, a historic ballpark, and I'm a real big fan of baseball, so it's one of those things that I couldn't ask for more."

Flynn credits his mother, Michele, with helping him find the right coaching growing up after his father passed away following a car accident.
